As posted elsewhere ( i will try and find link) twitter changed its interface requirements with iscore. Iscore developers have focused their efforts on the scorecast and iscore central app w premium option for more detailed play by play updating potential.

It would appear iscore development is moving more advanced play communication towards their scorecast rather than twittercast. Fans can view scorecasts via web browser or download siplay and iscore central viewer apps for both apple and android devices.
